Valve has added a new forfeit rule to its Counter-Strike 2 Tournament Operations Rulebook (TOR).
The CS2 developer has also adjusted other criteria relating to player lineups of teams that receive direct invitations to tournaments.
In an update published on October 13th, 2025, Valve added Rule 3.10.1 under the TOR’s Ranked Tournaments section.
The change reveals that tournament operators will “declare a forfeit in any match in which a roster does not field at least three of the invited roster athletes for the entirety of the match.”
The introduction of the rule means that three of the five players representing a roster when it receives an invitation to compete in a tournament must play in that event.
